N. Y., ASSIGNOB TO WOOD NEWSPAPER MACHINERY CORPORATION, OF NEW YORK, N.'Y., A CORPORATION OF VIRGINIA QUICK CHANGE SPLIGING DEVICEApplicationflled June4, 1927, Serial This invention relates to a pastingdevice for the web of a continuously operating printing press.

The principal objects of theinvention are to provide a single propellingmeans for propelling the expiring web roll up to the time of thesevering of the web and for propelling the fresh web roll previouslypasted and get it up to web speed before it is attached to the web, andto provide means for getting the fresh web roll up to web speed andcontinuing to rotate it as long as the web isconnected with it withoutchanging the propelling-device or shifting its engagement w1th the webroll from the time it is a fresh pasted roll to the time it is anexpiring roll stub. This obviously results in the reduction of mechanismand expense due to the fact that a single propelling device is used forthe fresh and expiring rolls instead of one for each one as has been thecase heretofore.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing in which Fig. 1 is adiagrammatic side view of a set of web rolls showing-my new method ofpropelling the running roll throughout the time of feeding a webtherefrom to the press;

Fig. 2 is a similar view showing the use of the same propelling meansfor starting. the fresh roll .and getting it up to web speed withoutlosing its control of the running or expiring roll; 1 f

Fig. 3 is a similar view showing the position of the parts after the*fresh roll is pasted to the expiring web and the latter severed;

Fig. 4 is a. similar view showing the removal of the core of theexpiring web roll and the commencement of the running of the web fromthe fresh roll, the parts being ready to shift back to the positionshown in Fig. 1; and

Fig. 5 is a side view of the fresh web roll pasted and illustrating thepropelling belts.

According to this invention, the web W is run to the press over aguide-roll G from a running web roll A. This running web roll REISSUEDNo. 196,517. Renewed March a, 1933.

provided with paste P in the usual manner. I have also shown aninecoming roll C which will later take the place of the roll B when thattakes the place of the roll A in the position just beyond that shown inFig. 4.

For the purpose of propelling the running roll A and the fresh roll B, Iprovide a series of driving belts D. These are indicated in thesefigures as running over pulleys on two shafts d, one of these shaftsbeing in stationary bearings, and the other being mounted to move towardand from the fresh roll B. The stationary shaft is operated from thepress at such a rate as to drive the belts at web speed. This movementabove mentioned is indicated by comparing Figs.

v1 and 2, in which the belts D, always in contact with the running orexpiring roll A, move into a position in Fig. 2 in vwhich they alsoengage the surface of the fresh roll B and rotate that soas to bring itup to web speed. After this is accomplished, the web W and the freshroll B are brought toward r each other by moving. one or the other asmay be desired. In the present instance, by comparison of Figs. 2 and 3it will be seen that the roll B has been moved up to the web.Furthermore, a means for pressing the web against the fresh roll, shownas taking the form of a brush E, has been moved up so that the expiringend of the web will be forced against the paste'stops P on the web Iroll B. Immediately afterwards, the'severing knife F is brought intocontact with the web and that is severed from the expiring roll or stubas shown in'Fig. 3. Now the expired roll or core A is removed as shownin Fig. 4, the knife F is drawn back and also the brush E. During allthis time the belts D have been running the roll B at web speed. Fromthe point shown in Fig. 4, the roll B becomes the running roll andeventually the expiring roll. The roll C is moved into the position ofthe roll B to become the fresh roll. at the desired time. It will beunderstood that the driving belts D can be moved as described or thefresh roll B can be moved so long as they are brought together. I havenot shown the means for moving these parts as they constitute the features of an independent invention. It will be seen that in all thesecases the expiring or running and fresh rolls are driven by a singlemeans constituting a plurality of driving belts rotated by the powerfrom a single shaft. There is no loss of control when a fresh rollbecomes the running roll. The only thing necessary to perform theabove-mentioned functions is to move this set of belts or the rolls tobe driven thereby.

This constitutes a simplified method of bringing the fresh roll up tothe web speed and keep the running and expiring roll running at webspeed all the time. Furthermore, by having only one driving means,

' there will be no possibility of the two ro-lls getting out of stepwith each other or being propelled at two different speeds.

Although I have illustrated and described only a single form of theinvention, I am aware of the fact that modifications can be made thereinby any person skilled in the art without departing from the scope of theinvention as expressed in the claims. Therefore, I. do not Wish to belimited to all the "details of construction herein shown and described,but what I do claim is 1. In a quick change splicing device, the

' combination with a running roll and a fresh roll for the web, of amoving member running at a constant speed and engaging the two rolls atdifferent points on its periphery and thus running the two rolls atexactly the same sun face speed, said moving member being connected withthe press to be operated thereby.

'2. In a quick change splicing device, the combination with a running orexpiring roll for the web, and afresh web roll, of a series ofpropelling belts engaging the surface'of the running or expiring roll atall times while it is connected with the running web and engaging thesurface of the fresh roll to run the fresh roll at web speed for amaterial period before going out of contact with the surface of theexpiring roll, said belts being movable out of contact with'the expiringroll at about the time which the web is severed therefrom.

of contact with the surface of the expiring roll until the web issevered.

' 4. In a web splicing mechanism, the comrooaata thereto and to continueto propel it until it is nearly exhausted, said belts being movable toaccommodate the roll in its splicing and running positions, and engagingthe surface of the expiring web roll at all times while it is deliveringthe web and the surface of the fresh roll without going out of contactwith the surface of the expiring roll while the latter is operating andthen passing out of contact with it. g

5. In a quick change splicing device, the combination with a runningroll and a fresh roll for the web, of a propelling belt running at aconstant speed ratio and simultaneously engaging the two rolls atdifferent points on its periphery, said propelling belt being connectedwith the press to be operated thereby.

6. The method of splicing a web. which consists in-runn'ing a surface atweb speed in contact-with the expiring web roll to r0- tate said webroll, then moving said surface until the rollis nearly exhausted, thenbringing said belt into contact with the fresh web roll, which has beenpasted, to bring that up to web speed, moving the fresh web roll tobring it into contact with the web, forcing the web against the freshWeb roll, severing. the web, and removing the exhausted stub fromcontact with said web, leaving the fresh web roll tov becontrolled bythe belt.

In testimony whereof I have hereunto affixed my signature.
